933 100 | ÷ | ( | 20 | − | x | ) | × | x | = | 927 100 |
方程两边同时乘以: | ( | 20 | − | x | ) |
933 100 | x | = | 927 100 | ( | 20 | − | x | ) |
933 100 | x | = | 927 100 | × | 20 | − | 927 100 | x |
933 100 | x | = | 927 5 | − | 927 100 | x |
933 100 | x | + | 927 100 | x | = | 927 5 |
93 5 | x | = | 927 5 |
x | = | 927 5 | ÷ | 93 5 |
= | 927 5 | × | 5 93 |
= | 309 | × | 1 31 |
x | = | 309 31 |
x | = | 9.967742 |
